BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention provides adeno-associated virus 4 (AAV4) and vectors derived therefrom. Thus, the present invention relates to AAV4 vectors for and methods of delivering nucleic acids to cells of subjects.

[0003] 1. Background Art

[0004] Adeno associated virus (AAV) is a small nonpathogenic virus of the parvoviridae family (for review see 28). AAV is distinct from the other members of this family by its dependence upon a helper virus for replication. In the absence of a helper virus, AAV may integrate in a locus specific manner into the q arm of chromosome 19 (21). The approximately 5 kb genome of AAV consists of one segment of single stranded DNA of either plus or minus polarity. The ends of the genome are short inverted terminal repeats which can fold into hairpin structures and serve as the origin of viral DNA replication. Physically, the parvovirus virion is non-enveloped and its icosohedral capsid is approximately 20 nm in diameter.

[0005] To date 7 serologically distinct AAVs have been identified and 5 have been isolated from humans or primates and are referred to as AAV types 1-5 (1). The most extensively studied of these isolates is AAV type 2 (AAV2). The genome of AAV2 is 4680 nucleotides in length and contains two open reading frames (ORFs). The left ORF encodes the non-structural Rep proteins, Rep40, Rep 52, Rep68 and Rep 78, which are involved in regulation of replication and transcription in addition to the production of single-stranded progeny genomes (5-8, 11, 12, 15, 17, 19, 21-23, 25, 34, 37-40). Furthermore, two of the Rep proteins have been associated with the preferential integration of AAV genomes into a region of the q arm of human chromosome 19. Rep68/78 have also been shown to possess NTP binding activity as well as DNA and RNA helicase activities. The Rep proteins possess a nuclear localization signal as well as several potential phosphorylation sites. Mutation of one of these kinase sites resulted in a loss of replication activity.

[0006] The ends of the genome are short inverted terminal repeats which have the potential to fold into T-shaped hairpin structures that serve as the origin of viral DNA replication. Within the ITR region two elements have been described which are central to the function of the ITR, a GAGC repeat motif and the terminal resolution site (trs). The repeat motif has been shown to bind Rep when the ITR is in either a linear or hairpin conformation (7, 8, 26). This binding serves to position Rep68/78 for cleavage at the trs which occurs in a site- and strand-specific manner. In addition to their role in replication, these two elements appear to be central to viral integration. Contained within the chromosome 19 integration locus is a Rep binding site with an adjacent trs. These elements have been shown to be functional and necessary for locus specific integration.

[0007] The AAV2 virion is a non-enveloped, icosohedral particle approximately 25 nm in diameter, consisting of three related proteins referred to as VPI,2 and 3. The right ORF encodes the capsid proteins, VP1, VP2, and VP3. These proteins are found in a ratio of 1:1:10 respectively and are all derived from the right-hand ORF. The capsid proteins differ from each other by the use of alternative splicing and an unusual start codon. Deletion analysis has shown that removal or alteration of VP1 which is translated from an alternatively spliced message results in a reduced yield of infections particles (15, 16, 38). Mutations within the VP3 coding region result in the failure to produce any single-stranded progeny DNA or infectious particles (15, 16, 38).

[0008] The following features of AAV have made it an attractive vector for gene transfer (16). AAV vectors have been shown in vitro to stably integrate into the cellular genome; possess a broad host range; transduce both dividing and non dividing cells in vitro and in vivo (13, 20, 30, 32) and maintain high levels of expression of the transduced genes (41). Viral particles are heat stable, resistant to solvents, detergents, changes in pH, temperature, and can be concentrated on CsCl gradients (1,2). Integration of AAV provirus is not associated with any long term negative effects on cell growth or differentiation (3,42). The ITRs have been shown to be the only cis elements required for replication, packaging and integration (3 5) and may contain some promoter activities (14).

[0009] Initial data indicate that AAV4 is a unique member of this family. DNA hybridization data indicated a similar level of homology for AAV1-4 (31). However, in contrast to the other AAVs only one ORF corresponding to the capsid proteins was identified in AAV4 and no ORF was detected for the Rep proteins (27).

[0010] AAV2 was originally thought to infect a wide variety of cell types provided the appropriate helper virus was present. Recent work has shown that some cell lines are transduced very poorly by AAV2 (30). While the receptor has not been completely characterized, binding studies have indicated that it is poorly expressed on erythroid cells (26). Recombinant AAV2 transduction of CD34⁺, bone marrow pluripotent cells, requires a multiplicity of infection (MOI) of 10⁴ particles per cell (A. W. Nienhuis unpublished results). This suggests that transduction is occurring by a non-specific mechanism or that the density of receptors displayed on the cell surface is low compared to other cell types.

[0011] The present invention provides a vector comprising the AAV4 virus as well as AAV4 viral particles. While AAV4 is similar to AAV2, the two viruses are found herein to be physically and genetically distinct. These differences endow AAV4 with some unique advantages which better suit it as a vector for gene therapy. For example, the wt AAV4 genome is larger than AAV2, allowing for efficient encapsidation of a larger recombinant genome. Furthermore, wt AAV4 particles have a greater buoyant density than AAV2 particles and therefore are more easily separated from contaminating helper virus and empty AAV particles than AAV2-based particles. Additionally, in contrast to AAV1, 2, and 3, AAV4, is able to hemagglutinate human, guinea pig, and sheep erythrocytes (18).

[0012] Furthermore, as shown herein, AAV4 capsid protein, again surprisingly, is distinct from AAV2 capsid protein and exhibits different tissue tropism. AAV2 and AAV4 have been shown to be serologically distinct and thus, in a gene therapy application, AAV4 would allow for transduction of a patient who already possess neutralizing antibodies to AAV2 either as a result of natural immunological defense or from prior exposure to AAV2 vectors. Thus, the present invention, by providing these new recombinant vectors and particles based on AAV4 provides a new and highly useful series of vectors.

BRIEF DESCRIPTION OF THE DRAWINGS

[0027]FIG. 1 shows a schematic outline of AAV 4. Promoters are indicated by horizontal arrows with their corresponding map positions indicated above. The polyadenylation site is indicated by a vertical arrow and the two open reading frames are indicated by black boxes. The splice region is indicated by a shaded box.

[0028]FIG. 2 shows AAV4 ITR. The sequence of the ITR (SEQ ID NO:20) is shown in the hairpin conformation. The putative Rep binding site is boxed. The cleavage site in the trs is indicated by an arrow. Bases which differ from the ITR of AAV2 are outlined.

[0029]FIG. 3 shows cotransduction of rAAV2 and rAAV4. Cos cells were transduced with a constant amount of rAAV2 or rAAV4 expressing beta galactosidase and increasing amounts of rAAV2 expressing human factor IX (rAAV2FIX) . For the competition the number of positive cells detected in the cotransduced wells was divided by the number of positive cells in the control wells (cells transduced with only rAAV2LacZ or rAAV4LacZ) and expressed as a percent of the control. This value was plotted against the number of particles of rAAV2FIX.

[0030]FIG. 4 shows effect of trypsin treatment on cos cell transduction. Cos cell monolayers were trypsinized and diluted in complete media. Cells were incubated with virus at an MOI of 260 and following cell attachment the virus was removed. As a control an equal number of cos cells were plated and allowed to attach overnight before transduction with virus for the same amount of time. The number of positive cells was determined by staining 50 hrs post transduction. The data is presented as a ratio of the number of positive cells seen with the trypsinized group and the control group.

DETAILED DESCRIPTION OF THE INVENTION

[0031] As used in the specification and in the claims, “a” can mean one or more, depending upon the context in which it is used.

[0032] The present invention provides the nucleotide sequence of the adeno-associated virus 4 (AAV4) genome and vectors and particles derived therefrom. Specifically, the present invention provides a nucleic acid vector comprising a pair of AAV4 inverted terminal repeats (ITRs) and a promoter between the inverted terminal repeats. The AAV4 ITRs are exemplified by the nucleotide sequence set forth in SEQ ID NO:6 and SEQ ID NO:20; however, these sequences can have minor modifications and still be contemplated to constitute AAV4 ITRs. The nucleic acid listed in SEQ ID NO:6 depicts the ITR in the “flip” orientation of the ITR. The nucleic acid listed in SEQ ID NO:20 depicts the ITR in the “flop” orientation of the ITR. Minor modifications in an ITR of either orientation are those that will not interfere with the hairpin structure formed by the AAV4 ITR as described herein and known in the art. Furthermore, to be considered within the term “AAV4 ITRs” the nucleotide sequence must retain the Rep binding site described herein and exemplified in SEQ ID NO:6 and SEQ ID NO:20, i.e., it must retain one or both features described herein that distinguish the AAV4 ITR from the AAV2 ITR: (1) four (rather than three as in AAV2) “GAGC” repeats and (2) in the AAV4 ITR Rep binding site the fourth nucleotide in the first two “GAGC” repeats is a T rather than a C.

[0033] The promoter can be any desired promoter, selected by known considerations, such as the level of expression of a nucleic acid functionally linked to the promoter and the cell type in which the vector is to be used. Promoters can be an exogenous or an endogenous promoter. Promoters can include, for example, known strong promoters such as SV40 or the inducible metallothionein promoter, or an AAV promoter, such as an AAV p5 promoter. Additional examples of promoters include promoters derived from actin genes, immunoglobulin genes, cytomegalovirus (CMV), adenovirus, bovine papilloma virus, adenoviral promoters, such as the adenoviral major late promoter, an inducible heat shock promoter, respiratory syncytial virus, Rous sarcomas virus (RSV), etc. Specifically, the promoter can be AAV2 p5 promoter or AAV4 p5 promoter. More specifically, the AAV4 p5 promoter can be about nucleotides 130 to 291 of SEQ ID NO:1. Additionally, the p5 promoter may be enhanced by nucleotides 1-130. Furthermore, smaller fragments of p5 promoter that retain promoter activity can readily be determined by standard procedures including, for example, constructing a series of deletions in the p5 promoter, linking the deletion to a reporter gene, and determining whether the reporter gene is expressed, i.e., transcribed and/or translated.

[0034] It should be recognized that the nucleotide and amino acid sequences set forth herein may contain minor sequencing errors. Such errors in the nucleotide sequences can be corrected, for example, by using the hybridization procedure described above with various probes derived from the described sequences such that the coding sequence can be reisolated and resequenced. The corresponding amino acid sequence can then be corrected accordingly.

[0035] The AAV4 vector can further comprise an exogenous nucleic acid functionally linked to the promoter. By “heterologous nucleic acid” is meant that any heterologous or exogenous nucleic acid can be inserted into the vector for transfer into a cell, tissue or organism. The nucleic acid can encode a polypeptide or protein or an antisense RNA, for example. By “functionally linked” is meant such that the promoter can promote expression of the heterologous nucleic acid, as is known in the art, such as appropriate orientation of the promoter relative to the heterologous nucleic acid. Furthermore, the heterologous nucleic acid preferably has all appropriate sequences for expression of the nucleic acid, as known in the art, to functionally encode, i.e., allow the nucleic acid to be expressed. The nucleic acid can include, for example, expression control sequences, such as an enhancer, and necessary information processing sites, such as ribosome binding sites, RNA splice sites, polyadenylation sites, and transcriptional terminator sequences.

[0036] The heterologous nucleic acid can encode beneficial proteins that replace missing or defective proteins required by the subject into which the vector in transferred or can encode a cytotoxic polypeptide that can be directed, e.g., to cancer cells or other cells whose death would be beneficial to the subject. The heterologous nucleic acid can also encode antisense RNAs that can bind to, and thereby inactivate, mRNAs made by the subject that encode harmful proteins. In one embodiment, antisense polynucleotides can be produced from a heterologous expression cassette in an AAV4 viral construct where the expression cassette contains a sequence that promotes cell-type specific expression (Wirak et al., EMBO 10:289 (1991)). For general methods relating to antisense polynucleotides, see Antisense RNA and DNA, D. A. Melton, Ed., Cold Spring Harbor Laboratory, Cold Spring Harbor, N.Y. (1988).

[0037] Examples of heterologous nucleic acids which can be administered to a cell or subject as part of the present AAV4 vector can include, but are not limited to the following: nucleic acids encoding therapeutic agents, such as tumor necrosis factors (TNF), such as TNF-α; interferons, such as interferon-α, interferon-β, and interferon-γ; interleukins, such as IL-1, IL-1β, and ILs −2 through −14; GM-CSF; adenosine deaminase; cellular growth factors, such as lymphokines; soluble CD4; Factor VIII; Factor IX; T-cell receptors; LDL receptor; ApoE; ApoC; alpha-1 antitrypsin; ornithine transcarbamylase (OTC); cystic fibrosis transmembrane receptor (CFTR); insulin; Fc receptors for antigen binding domains of antibodies, such as immunoglobulins; and antisense sequences which inhibit viral replication, such as antisense sequences which inhibit replication of hepatitis B or hepatitis non-A, non-B virus. The nucleic acid is chosen considering several factors, including the cell to be transfected. Where the target cell is a blood cell, for example, particularly useful nucleic acids to use are those which allow the blood cells to exert a therapeutic effect, such as a gene encoding a clotting factor for use in treatment of hemophilia. Furthermore, the nucleic acid can encode more than one gene product, limited only, if the nucleic acid is to be packaged in a capsid, by the size of nucleic acid that can be packaged.

[0038] Furthermore, suitable nucleic acids can include those that, when transferred into a primary cell, such as a blood cell, cause the transferred cell to target a site in the body where that cell's presence would be beneficial. For example, blood cells such as TIL cells can be modified, such as by transfer into the cell of a Fab portion of a monoclonal antibody, to recognize a selected antigen. Another example would be to introduce a nucleic acid that would target a therapeutic blood cell to tumor cells. Nucleic acids useful in treating cancer cells include those encoding chemotactic factors which cause an inflammatory response at a specific site, thereby having a therapeutic effect.

[0039] Cells, particularly blood cells, having such nucleic acids transferred into them can be useful in a variety of diseases, syndromes and conditions. For example, suitable nucleic acids include nucleic acids encoding soluble CD4, used in the treatment of AIDS and α-antitrypsin, used in the treatment of emphysema caused by α-antitrypsin deficiency. Other diseases, syndromes and conditions in which such cells can be useful include, for example, adenosine deaminase deficiency, sickle cell deficiency, brain disorders such as Alzheimer's disease, thalassemia, hemophilia, diabetes, phenylketonuria, growth disorders and heart diseases, such as those caused by alterations in cholesterol metabolism, and defects of the immune system.

[0040] As another example, hepatocytes can be transfected with the present vectors having useful nucleic acids to treat liver disease. For example, a nucleic acid encoding OTC can be used to transfect hepatocytes (ex vivo and returned to the liver or in vivo) to treat congenital hyperammonemia, caused by an inherited deficiency in OTC. Another example is to use a nucleic acid encoding LDL to target hepatocytes ex vivo or in vivo to treat inherited LDL receptor deficiency. Such transfected hepatocytes can also be used to treat acquired infectious diseases, such as diseases resulting from a viral infection. For example, transduced hepatocyte precursors can be used to treat viral hepatitis, such as hepatitis B and non-A, non-B hepatitis, for example by transducing the hepatocyte precursor with a nucleic acid encoding an antisense RNA that inhibits viral replication. Another example includes transferring a vector of the present invention having a nucleic acid encoding a protein, such as α-interferon, which can confer resistance to the hepatitis virus.

[0041] For a procedure using transfected hepatocytes or hepatocyte precursors, hepatocyte precursors having a vector of the present invention transferred in can be grown in tissue culture, removed form the tissue culture vessel, and introduced to the body, such as by a surgical method. In this example, the tissue would be placed directly into the liver, or into the body cavity in proximity to the liver, as in a transplant or graft. Alternatively, the cells can simply be directly injected into the liver, into the portal circulatory system, or into the spleen, from which the cells can be transported to the liver via the circulatory system. Furthermore, the cells can be attached to a support, such as microcarrier beads, which can then be introduced, such as by injection, into the peritoneal cavity. Once the cells are in the liver, by whatever means, the cells can then express the nucleic acid and/or differentiate into mature hepatocytes which can express the nucleic acid.

[0042] The present invention also contemplates any unique fragment of these AAV4 nucleic acids, including the AAV4 nucleic acids set forth in SEQ ID NOs: 1, 3, 5, 6, 7, 12-15, 17 and 19. To be unique, the fragment must be of sufficient size to distinguish it from other known sequences, most readily determined by comparing any nucleic acid fragment to the nucleotide sequences of nucleic acids in computer databases, such as GenBank. Such comparative searches are standard in the art. Typically, a unique fragment useful as a primer or probe will be at least about 8 or 10 to about 20 or 25 nucleotides in length, depending upon the specific nucleotide content of the sequence. Additionally, fragments can be, for example, at least about 30, 40, 50, 75, 100, 200 or 500 nucleotides in length. The nucleic acid can be single or double stranded, depending upon the purpose for which it is intended.

[0043] The present invention further provides an AAV4 capsid protein. In particular, the present invention provides not only a polypeptide comprising all three AAV4 coat proteins, i.e., VP1, VP2 and VP3, but also a polypeptide comprising each AAV4 coat protein individually. Thus an AAV4 particle comprising an AAV4 capsid protein comprises at least one AAV4 coat protein VP1, VP2 or VP3. An AAV4 particle comprising an AAV4 capsid protein can be utilized to deliver a nucleic acid vector to a cell, tissue or subject. For example, the herein described AAV4 vectors can be encapsulated in an AAV4 particle and utilized in a gene delivery method. Furthermore, other viral nucleic acids can be encapsidated in the AAV4 particle and utilized in such delivery methods. For example, an AAV2 vector can be encapsidated in an AAV4 particle and administered. Furthermore, a chimeric capsid protein incorporating both AAV2 and AAV4 sequences can be generated, by standard cloning methods, selecting regions from each protein as desired. For example, particularly antigenic regions of the AAV2 capsid protein can be replaced with the corresponding region of the AAV4 capsid protein.

[0044] The herein described AAV4 nucleic acid vector can be encapsidated in an AAV particle. In particular, it can be encapsidated in an AAV1 particle, an AAV2 particle, an AAV3 particle, an AAV4 particle, or an AAV5 particle by standard methods using the appropriate capsid proteins in the encapsidation process, as long as the nucleic acid vector fits within the size limitation of the particle utilized. The encapsidation process itself is standard in the art.

[0045] An AAV4 particle is a viral particle comprising an AAV4 capsid protein. An AAV4 capsid polypeptide encoding the entire VP1, VP2, and VP3 polypeptide can overall have at least about 63% homology to the polypeptide having the amino acid sequence encoded by nucleotides 2260-4464 set forth in SEQ ID NO:1 (AAV4 capsid protein). The capsid protein can have about 70% homology, about 75% homology, 80% homology, 85% homology, 90% homology, 95% homology, 98% homology, 99% homology, or even 100% homology to the protein having the amino acid sequence encoded by nucleotides 2260-4464 set forth in SEQ ID NO:1. The particle can be a particle comprising both AAV4 and AAV2 capsid protein, i.e., a chimeric protein. Variations in the amino acid sequence of the AAV4 capsid protein are contemplated herein, as long as the resulting viral particle comprising the AAV4 capsid remains antigenically or immunologically distinct from AAV2, as can be routinely determined by standard methods. Specifically, for example, ELISA and Western blots can be used to determine whether a viral particle is antigenically or immunologically distinct from AAV2. Furthermore, the AAV4 viral particle preferably retains tissue tropism distinction from AAV2, such as that exemplified in the examples herein, though an AAV4 chimeric particle comprising at least one AAV4 coat protein may have a different tissue tropism from that of an AAV4 particle consisting only of AAV4 coat proteins.

[0046] The invention further provides an AAV4 particle containing, i.e., encapsidating, a vector comprising a pair of AAV2 inverted terminal repeats. The nucleotide sequence of AAV2 ITRs is known in the art. Furthermore, the particle can be a particle comprising both AAV4 and AAV2 capsid protein, i.e., a chimeric protein. The vector encapsidated in the particle can further comprise an exogenous nucleic acid inserted between the inverted terminal repeats.

[0047] The present invention further provides an isolated nucleic acid comprising the nucleotide sequence set forth in SEQ ID NO:1 (AAV4 genome). This nucleic acid, or portions thereof, can be inserted into other vectors, such as plasmids, yeast artificial chromosomes, or other viral vectors, if desired, by standard cloning methods. The present invention also provides an isolated nucleic acid consisting essentially of the nucleotide sequence set forth in SEQ ID NO:1. The nucleotides of SEQ ID NO:1 can have minor modifications and still be contemplated by the present invention. For example, modifications that do not alter the amino acid encoded by any given codon (such as by modification of the third, “wobble,” position in a codon) can readily be made, and such alterations are known in the art. Furthermore, modifications that cause a resulting neutral amino acid substitution of a similar amino acid can be made in a coding region of the genome. Additionally, modifications as described herein for the AAV4 components, such as the ITRs, the p5 promoter, etc. are contemplated in this invention.

[0048] The present invention additionally provides an isolated nucleic acid that selectively hybridizes with an isolated nucleic acid consisting essentially of the nucleotide sequence set forth in SEQ ID NO:1 (AAV4 genome). The present invention further provides an isolated nucleic acid that selectively hybridizes with an isolated nucleic acid comprising the nucleotide sequence set forth in SEQ ID NO:1 (AAV4 genome). By “selectively hybridizes” as used in the claims is meant a nucleic acid that specifically hybridizes to the particular target nucleic acid under sufficient stringency conditions to selectively hybridize to the target nucleic acid without significant background hybridization to a nucleic acid encoding an unrelated protein, and particularly, without detectably hybridizing to AAV2. Thus, a nucleic acid that selectively hybridizes with a nucleic acid of the present invention will not selectively hybridize under stringent conditions with a nucleic acid encoding a different protein, and vice versa. Therefore, nucleic acids for use, for example, as primers and probes to detect or amplify the target nucleic acids are contemplated herein. Nucleic acid fragments that selectively hybridize to any given nucleic acid can be used, e.g., as primers and or probes for further hybridization or for amplification methods (e.g., polymerase chain reaction (PCR), ligase chain reaction (LCR)). Additionally, for example, a primer or probe can be designed that selectively hybridizes with both AAV4 and a gene of interest carried within the AAV4 vector (i.e., a chimeric nucleic acid).

[0049] Stringency of hybridization is controlled by both temperature and salt concentration of either or both of the hybridization and washing steps. Typically, the stringency of hybridization to achieve selective hybridization involves hybridization in high ionic strength solution (6×SSC or 6×SSPE) at a temperature that is about 12-25° C. below the T_(m) (the melting temperature at which half of the molecules dissociate from its partner) followed by washing at a combination of temperature and salt concentration chosen so that the washing temperature is about 5° C. to 20° C. below the T_(m) The temperature and salt conditions are readily determined empirically in preliminary experiments in which samples of reference DNA immobilized on filters are hybridized to a labeled nucleic acid of interest and then washed under conditions of different stringencies. Hybridization temperatures are typically higher for DNA-RNA and RNA-RNA hybridizations. The washing temperatures can be used as described above to achieve selective stringency, as is known in the art. (Sambrook et al., Molecular Cloning: A Laboratory Manual, 2nd Ed., Cold Spring Harbor Laboratory, Cold Spring Harbor, N.Y., 1989; Kunkel et al. Methods Enzymol. 1987:154:367, 1987). A preferable stringent hybridization condition for a DNA:DNA hybridization can be at about 68° C. (in aqueous solution) in 6×SSC or 6×SSPE followed by washing at 68° C. Stringency of hybridization and washing, if desired, can be reduced accordingly as homology desired is decreased, and further, depending upon the G-C or A-T richness of any area wherein variability is searched for. Likewise, stringency of hybridization and washing, if desired, can be increased accordingly as homology desired is increased, and further, depending upon the G-C or A-T richness of any area wherein high homology is desired, all as known in the art.

[0050] A nucleic acid that selectively hybridizes to any portion of the AAV4 genome is contemplated herein. Therefore, a nucleic acid that selectively hybridizes to AAV4 can be of longer length than the AAV4 genome, it can be about the same length as the AAV4 genome or it can be shorter than the AAV4 genome. The length of the nucleic acid is limited on the shorter end of the size range only by its specificity for hybridization to AAV4, i.e., once it is too short, typically less than about 5 to 7 nucleotides in length, it will no longer bind specifically to AAV4, but rather will hybridize to numerous background nucleic acids. Additionally contemplated by this invention is a nucleic acid that has a portion that specifically hybridizes to AAV4 and a portion that specifically hybridizes to a gene of interest inserted within AAV4.

[0051] The present invention further provides an isolated nucleic acid encoding an adeno-associated virus 4 Rep protein. The AAV4 Rep proteins are encoded by open reading frame (ORF) 1 of the AAV4 genome. The AAV4 Rep genes are exemplified by the nucleic acid set forth in SEQ ID NO:3 (AAV4 ORF1), and include a nucleic acid consisting essentially of the nucleotide sequence set forth in SEQ ID NO:3 and a nucleic acid comprising the nucleotide sequence set forth in SEQ ID NO:3. The present invention also includes a nucleic acid encoding the amino acid sequence set forth in SEQ ID NO:2 (polypeptide encoded by AAV4 ORF1). However, the present invention includes that the Rep genes nucleic acid can include any one, two, three, or four of the four Rep proteins, in any order, in such a nucleic acid. Furthermore, minor modifications are contemplated in the nucleic acid, such as silent mutations in the coding sequences, mutations that make neutral or conservative changes in the encoded amino acid sequence, and mutations in regulatory regions that do not disrupt the expression of the gene. Examples of other minor modifications are known in the art. Further modifications can be made in the nucleic acid, such as to disrupt or alter expression of one or more of the Rep proteins in order to, for example, determine the effect of such a disruption; such as to mutate one or more of the Rep proteins to determine the resulting effect, etc. However, in general, a modified nucleic acid encoding all four Rep proteins will have at least about 90%, about 93%, about 95%, about 98% or 100% homology to the sequence set forth in SEQ ID NO:3, and the Rep polypeptide encoded therein will have overall about 93%, about 95%, about 98%, about 99% or 100% homology with the amino acid sequence set forth in SEQ ID NO:2.

[0052] The present invention also provides an isolated nucleic acid that selectively hybridizes with a nucleic acid consisting essentially of the nucleotide sequence set forth in SEQ ID NO:3 and an isolated nucleic acid that selectively hybridizes with a nucleic acid comprising the nucleotide sequence set forth in SEQ ID NO:3. “Selectively hybridizing” is defined elsewhere herein.

[0053] The present invention also provides each individual AAV4 Rep protein and the nucleic acid encoding each. Thus the present invention provides the nucleic acid encoding a Rep 40 protein, and in particular an isolated nucleic acid comprising the nucleotide sequence set forth in SEQ ID NO:12, an isolated nucleic acid consisting essentially of the nucleotide sequence set forth in SEQ ID NO:12, and a nucleic acid encoding the adeno-associated virus 4 Rep protein having the amino acid sequence set forth in SEQ ID NO:8. The present invention also provides the nucleic acid encoding a Rep 52 protein, and in particular an isolated nucleic acid comprising the nucleotide sequence set forth in SEQ ID NO:13, an isolated nucleic acid consisting essentially of the nucleotide sequence set forth in SEQ ID NO:13, and a nucleic acid encoding the adeno-associated virus 4 Rep protein having the amino acid sequence set forth in SEQ ID NO:9. The present invention further provides the nucleic acid encoding a Rep 68 protein, and in particular an isolated nucleic acid comprising the nucleotide sequence set forth in SEQ ID NO:14, an isolated nucleic acid consisting essentially of the nucleotide sequence set forth in SEQ ID NO:14, and a nucleic acid encoding the adeno-associated virus 4 Rep protein having the amino acid sequence set forth in SEQ ID NO:10. And, further, the present invention provides the nucleic acid encoding a Rep 78 protein, and in particular an isolated nucleic acid comprising the nucleotide sequence set forth in SEQ ID NO:15, an isolated nucleic acid consisting essentially of the nucleotide sequence set forth in SEQ ID NO:15, and a nucleic acid encoding the adeno-associated virus 4 Rep protein having the amino acid sequence set forth in SEQ ID NO:11. As described elsewhere herein, these nucleic acids can have minor modifications, including silent nucleotide substitutions, mutations causing neutral amino acid substitutions in the encoded proteins, and mutations in control regions that do not or minimally affect the encoded amino acid sequence.

[0054] The present invention further provides a nucleic acid encoding the entire AAV4 Capsid polypeptide. Specifically, the present invention provides a nucleic acid having the nucleotide sequence set for the nucleotides 2260-4464 of SEQ ID NO:1. Furthermore, the present invention provides a nucleic acid encoding each of the three AAV4 coat proteins, VP1, VP2, and VP3. Thus, the present invention provides a nucleic acid encoding AAV4 VP1, a nucleic acid encoding AAV4 VP2, and a nucleic acid encoding AAV4 VP3. Thus, the present invention provides a nucleic acid encoding the amino acid sequence set forth in SEQ ID NO:4 (VP1); a nucleic acid encoding the amino acid sequence set forth in SEQ ID NO:16 (VP2), and a nucleic acid encoding the amino acid sequence set forth in SEQ ID NO:18 (VP3). The present invention also specifically provides a nucleic acid comprising SEQ ID NO:5 (VP1 gene); a nucleic acid comprising SEQ ID NO:17 (VP2 gene); and a nucleic acid comprising SEQ ID NO:19 (VP3 gene). The present invention also specifically provides a nucleic acid consisting essentially of SEQ ID NO:5 (VP1 gene), a nucleic acid consisting essentially of SEQ ID NO:17 (VP2 gene), and a nucleic acid consisting essentially of SEQ ID NO:19 (VP3 gene). Furthermore, a nucleic acid encoding an AAV4 capsid protein VP1 is set forth as nucleotides 2157-4361 of SEQ ID NO:1; a nucleic acid encoding an AAV4 capsid protein VP2 is set forth as nucleotides 2565-4361 of SEQ ID NO:1; and a nucleic acid encoding an AAV4 capsid protein VP3 is set forth as nucleotides 2745-4361 of SEQ ID NO:1. Minor modifications in the nucleotide sequences encoding the capsid, or coat, proteins are contemplated, as described above for other AAV4 nucleic acids.

[0055] The present invention also provides a cell containing one or more of the herein described nucleic acids, such as the AAV4 genome, AAV4 ORF1 and ORF2, each AAV4 Rep protein gene, and each AAV4 capsid protein gene. Such a cell can be any desired cell and can be selected based upon the use intended. For example, cells can include human HeLa cells, cos cells, other human and mammalian cells and cell lines. Primary cultures as well as established cultures and cell lines can be used. Nucleic acids of the present invention can be delivered into cells by any selected means, in particular depending upon the target cells. Many delivery means are well-known in the art. For example, electroporation, calcium phosphate precipitation, microinjection, cationic or anionic liposomes, and liposomes in combination with a nuclear localization signal peptide for delivery to the nucleus can be utilized, as is known in the art. Additionally, if in a viral particle, the cells can simply be transfected with the particle by standard means known in the art for AAV transfection.

[0056] The term “polypeptide” as used herein refers to a polymer of amino acids and includes fill-length proteins and fragments thereof. Thus, “protein,” “polypeptide,” and “peptide” are often used interchangeably herein. Substitutions can be selected by known parameters to be neutral (see, e.g., Robinson W E Jr, and Mitchell W M., AIDS 4:S151-S162 (1990)). As will be appreciated by those skilled in the art, the invention also includes those polypeptides having slight variations in amino acid sequences or other properties. Such variations may arise naturally as allelic variations (e.g., due to genetic polymorphism) or may be produced by human intervention (e.g., by mutagenesis of cloned DNA sequences), such as induced point, deletion, insertion and substitution mutants. Minor changes in amino acid sequence are generally preferred, such as conservative amino acid replacements, small internal deletions or insertions, and additions or deletions at the ends of the molecules. Substitutions may be designed based on, for example, the model of Dayhoff, et al. (in Atlas of Protein Sequence and Structure 1978, Nat'l Biomed. Res. Found., Washington, D.C.). These modifications can result in changes in the amino acid sequence, provide silent mutations, modify a restriction site, or provide other specific mutations.

[0057] A polypeptide of the present invention can be readily obtained by any of several means. For example, polypeptide of interest can be synthesized mechanically by standard methods. Additionally, the coding regions of the genes can be expressed and the resulting polypeptide isolated by standard methods. Furthermore, an antibody specific for the resulting polypeptide can be raised by standard methods (see, e.g., Harlow and Lane, Antibodies: A Laboratory Manual, Cold Spring Harbor Laboratory, Cold Spring Harbor, N.Y., 1988), and the protein can be isolated from a cell expressing the nucleic acid encoding the polypeptide by selective hybridization with the antibody. This protein can be purified to the extent desired by standard methods of protein purification (see, e.g., Sambrook et al., Molecular Cloning: A Laboratory Manual, 2nd Ed., Cold Spring Harbor Laboratory, Cold Spring Harbor, N.Y., 1989).

[0058] Typically, to be unique, a polypeptide fragment of the present invention will be at least about 5 amino acids in length; however, unique fragments can be 6, 7, 8, 9, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 or more amino acids in length. A unique polypeptide will typically comprise such a unique fragment; however, a unique polypeptide can also be determined by its overall homology. A unique polypeptide can be 6, 7, 8, 9, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 or more amino acids in length. Uniqueness of a polypeptide fragment can readily be determined by standard methods such as searches of computer databases of known peptide or nucleic acid sequences or by hybridization studies to the nucleic acid encoding the protein or to the protein itself, as known in the art.

[0059] The present invention provides an isolated AAV4 Rep protein. AAV4 Rep polypeptide is encoded by ORF1 of AAV4. Specifically, the present invention provides an AAV4 Rep polypeptide comprising the amino acid sequence set forth in SEQ ID NO:2, or a unique fragment thereof. The present invention also provides an AAV4 Rep polypeptide consisting essentially of the amino acid sequence set forth in SEQ ID NO:2, or a unique fragment thereof Additionally, nucleotides 291-2306 of the AAV4 genome, which genome is set forth in SEQ ID NO:1, encode the AAV4 Rep polypeptide. The present invention also provides each AAV4 Rep protein. Thus the present invention provides AAV4 Rep 40, or a unique fragment thereof. The present invention particularly provides Rep 40 having the amino acid sequence set forth in SEQ ID NO:8. The present invention provides AAV4 Rep 52, or a unique fragment thereof. The present invention particularly provides Rep 52 having the amino acid sequence set forth in SEQ ID NO:9. The present invention provides AAV4 Rep 68, or a unique fragment thereof The present invention particularly provides Rep 68 having the amino acid sequence set forth in SEQ ID NO:10. The present invention provides AAV4 Rep 78, or a unique fragment thereof The present invention particularly provides Rep 78 having the amino acid sequence set forth in SEQ ID NO:11. By “unique fragment thereof” is meant any smaller polypeptide fragment encoded by AAV rep gene that is of sufficient length to be unique to the Rep polypeptide. Substitutions and modifications of the amino acid sequence can be made as described above and, further, can include protein processing modifications, such as glycosylation, to the polypeptide. However, a polypeptide including all four Rep proteins will encode a polypeptide having at least about 91% overall homology to the sequence set forth in SEQ ID NO:2, and it can have about 93%, about 95%, about 98%, about 99% or 100% homology with the amino acid sequence set forth in SEQ ID NO:2.

[0060] The present invention further provides an AAV4 Capsid polypeptide or a unique fragment thereof AAV4 capsid polypeptide is encoded by ORF 2 of AAV4. Specifically, the present invention provides an AAV4 Capsid protein comprising the amino acid sequence encoded by nucleotides 2260-4464 of the nucleotide sequence set forth in SEQ ID NO:1, or a unique fragment of such protein. The present invention also provides an AAV4 Capsid protein consisting essentially of the amino acid sequence encoded by nucleotides 2260-4464 of the nucleotide sequence set forth in SEQ ID NO:1, or a unique fragment of such protein. The present invention further provides the individual AAV4 coat proteins, VP1, VP2 and VP3. Thus, the present invention provides an isolated polypeptide having the amino acid sequence set forth in SEQ ID NO:4 (VP1). The present invention additionally provides an isolated polypeptide having the amino acid sequence set forth in SEQ ID NO:16 (VP2). The present invention also provides an isolated polypeptide having the amino acid sequence set forth in SEQ ID NO:18 (VP3). By “unique fragment thereof” is meant any smaller polypeptide fragment encoded by any AAV4 capsid gene that is of sufficient length to be unique to the AAV4 Capsid protein. Substitutions and modifications of the amino acid sequence can be made as described above and, further, can include protein processing modifications, such as glycosylation, to the polypeptide. However, an AAV4 Capsid polypeptide including all three coat proteins will have at least about 63% overall homology to the polypeptide encoded by nucleotides 2260-4464 of the sequence set forth in SEQ ID NO:1. The protein can have about 65%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95% or even 100% homology to the amino acid sequence encoded by the nucleotides 2260-4464 of the sequence set forth in SEQ ID NO:4. An AAV4 VP2 polypeptide can have at least about 58%, about 60%, about 70%, about 80%, about 90% about 95% or about 100% homology to the amino acid sequence set forth in SEQ ID NO:16. An AAV4 VP3 polypeptide can have at least about 60%, about 70%, about 80%, about 90% about 95% or about 100% homology to the amino acid sequence set forth in SEQ ID NO:18.

[0061] The present invention further provides an isolated antibody that specifically binds AAV4 Rep protein. Also provided is an isolated antibody that specifically binds the AAV4 Rep protein having the amino acid sequence set forth in SEQ ID NO:2, or that specifically binds a unique fragment thereof. Clearly, any given antibody can recognize and bind one of a number of possible epitopes present in the polypeptide; thus only a unique portion of a polypeptide (having the epitope) may need to be present in an assay to determine if the antibody specifically binds the polypeptide.

[0062] The present invention additionally provides an isolated antibody that specifically binds any adeno-associated virus 4 Capsid protein or the polypeptide comprising all three AAV4 coat proteins. Also provided is an isolated antibody that specifically binds the AAV4 Capsid protein having the amino acid sequence set forth in SEQ ID NO:4, or that specifically binds a unique fragment thereof. The present invention further provides an isolated antibody that specifically binds the AAV4 Capsid protein having the amino acid sequence set forth in SEQ ID NO:16, or that specifically binds a unique fragment thereof. The invention additionally provides an isolated antibody that specifically binds the AAV4 Capsid protein having the amino acid sequence set forth in SEQ ID NO:18, or that specifically binds a unique fragment thereof. Again, any given antibody can recognize and bind one of a number of possible epitopes present in the polypeptide; thus only a unique portion of a polypeptide (having the epitope) may need to be present in an assay to determine if the antibody specifically binds the polypeptide.

[0063] The antibody can be a component of a composition that comprises an antibody that specifically binds the AAV4 protein. The composition can further comprise, e.g., serum, serum-free medium, or a pharmaceutically acceptable carrier such as physiological saline, etc.

[0064] By “an antibody that specifically binds” an AAV4 polypeptide or protein is meant an antibody that selectively binds to an epitope on any portion of the AAV4 peptide such that the antibody selectively binds to the AAV4 polypeptide, i.e., such that the antibody binds specifically to the corresponding AAV4 polypeptide without significant background. Specific binding by an antibody further means that the antibody can be used to selectively remove the target polypeptide from a sample comprising the polypeptide or and can readily be determined by radioimmuno assay (RIA), bioassay, or enzyme-linked immunosorbant (ELISA) technology. An ELISA method effective for the detection of the specific antibody-antigen binding can, for example, be as follows: (1) bind the antibody to a substrate; (2) contact the bound antibody with a sample containing the antigen; (3) contact the above with a secondary antibody bound to a detectable moiety (e.g., horseradish peroxidase enzyme or alkaline phosphatase enzyme); (4) contact the above with the substrate for the enzyme; (5) contact the above with a color reagent; (6) observe the color change.

[0065] An antibody can include antibody fragments such as Fab fragments which retain the binding activity. Antibodies can be made as described in, e.g., Harlow and Lane, Antibodies: A Laboratory Manual, Cold Spring Harbor Laboratory, Cold Spring Harbor, N.Y. (1988). Briefly, purified antigen can be injected into an animal in an amount and in intervals sufficient to elicit an immune response. Antibodies can either be purified directly, or spleen cells can be obtained from the animal. The cells are then fused with an immortal cell line and screened for antibody secretion. Individual hybridomas are then propagated as individual clones serving as a source for a particular monoclonal antibody.

[0066] The present invention additionally provides a method of screening a cell for infectivity by AAV4 comprising contacting the cell with AAV4 and detecting the presence of AAV4 in the cells. AAV4 particles can be detected using any standard physical or biochemical methods. For example, physical methods that can be used for this detection include 1) polymerase chain reaction (PCR) for viral DNA or RNA, 2) direct hybridization with labeled probes, 3) antibody directed against the viral structural or non-structural proteins. Catalytic methods of viral detection include, but are not limited to, detection of site and strand specific DNA nicking activity of Rep proteins or replication of an AAV origin-containing substrate. Additional detection methods are outlined in Fields, Virology, Raven Press, New York, N.Y. 1996.

[0067] For screening a cell for infectivity by AAV4 wherein the presence of AAV4 in the cells is determined by nucleic acid hybridization methods, a nucleic acid probe for such detection can comprise, for example, a unique fragment of any of the AAV4 nucleic acids provided herein. The uniqueness of any nucleic acid probe can readily be determined as described herein for unique nucleic acids. The nucleic acid can be, for example, the nucleic acid whose nucleotide sequence is set forth in SEQ ID NO:1, 3, 5, 6, 7, 12, 13, 14, 15, 17 or 19, or a unique fragment thereof.

[0068] The present invention includes a method of determining the suitability of an AAV4 vector for administration to a subject comprising administering to an antibody-containing sample from the subject an antigenic fragment of an isolated AAV4 capsid protein, and detecting an antibody-antigen reaction in the sample, the presence of a reaction indicating the AAV4 vector to be unsuitable for use in the subject. The AAV4 capsid protein from which an antigenic fragment is selected can have the amino acid sequence set forth in SEQ ID NO:4. An immunogenic fragment of an isolated AAV4 capsid protein can also be used in these methods. The AAV4 capsid protein from which an antigenic fragment is selected can have the amino acid sequence set forth in SEQ ID NO:17. The AAV4 capsid protein from which an antigenic fragment is selected can have the amino acid sequence set forth in SEQ ID NO:19.

[0069] Alternatively, or additionally, an antigenic fragment of an isolated AAV4 Rep protein can be utilized in this determination method. An immunogenic fragment of an isolated AAV4 Rep protein can also be used in these methods. Thus the present invention further provides a method of determining the suitability of an AAV4 vector for administration to a subject comprising administering to an antibody-containing sample from the subject an antigenic fragment of an AAV4 Rep protein and detecting an antibody-antigen reaction in the sample, the presence of a reaction indicating the AAV4 vector to be unsuitable for use in the subject. The AAV4 Rep protein from which an antigenic fragment is selected can have the amino acid sequence set forth in SEQ ID NO:2. The AAV4 Rep protein from which an antigenic fragment is selected can have the amino acid sequence set forth in SEQ ID NO:8. The AAV4 Rep protein from which an antigenic fragment is selected can have the amino acid sequence set forth in SEQ ID NO:9. The AAV4 Rep protein from which an antigenic fragment is selected can have the amino acid sequence set forth in SEQ ID NO:10. The AAV4 Rep protein from which an antigenic fragment is selected can have the amino acid sequence set forth in SEQ ID NO:11.

[0070] An antigenic or immunoreactive fragment is typically an amino acid sequence of at least about 5 consecutive amino acids, and it can be derived from the AAV4 polypeptide amino acid sequence. An antigenic fragment is any fragment unique to the AAV4 protein, as described herein, against which an AAV4-specific antibody can be raised, by standard methods. Thus, the resulting antibody-antigen reaction should be specific for AAV4.

[0071] The AAV4 polypeptide fragments can be analyzed to determine their antigenicity, immunogenicity and/or specificity. Briefly, various concentrations of a putative immunogenically specific fragment are prepared and administered to a subject and the immunological response (e.g., the production of antibodies or cell mediated immunity) of an animal to each concentration is determined. The amounts of antigen administered depend on the subject, e.g. a human, rabbit or a guinea pig, the condition of the subject, the size of the subject, etc. Thereafter an animal so inoculated with the antigen can be exposed to the AAV4 viral particle or AAV4 protein to test the immunoreactivity or the antigenicity of the specific immunogenic fragment. The specificity of a putative antigenic or immunogenic fragment can be ascertained by testing sera, other fluids or lymphocytes from the inoculated animal for cross reactivity with other closely related viruses, such as AAV1, AAV2, AAV3 and AAV5.

[0072] As will be recognized by those skilled in the art, numerous types of immunoassays are available for use in the present invention to detect binding between an antibody and an AAV4 polypeptide of this invention. For instance, direct and indirect binding assays, competitive assays, sandwich assays, and the like, as are generally described in, e.g., U.S. Pat. Nos. 4,642,285; 4,376,110; 4,016,043; 3,879,262; 3,852,157; 3,850,752; 3,839,153; 3,791,932; and Harlow and Lane, Antibodies, A Laboratory Manual, Cold Spring Harbor Publications, N.Y. (1988). For example, enzyme immunoassays such as immunofluorescence assays (IFA), enzyme linked immunosorbent assays (ELISA) and immunoblotting can be readily adapted to accomplish the detection of the antibody. An ELISA method effective for the detection of the antibody bound to the antigen can, for example, be as follows: (1) bind the antigen to a substrate; (2) contact the bound antigen with a fluid or tissue sample containing the antibody; (3) contact the above with a secondary antibody specific for the antigen and bound to a detectable moiety (e.g., horseradish peroxidase enzyme or alkaline phosphatase enzyme); (4) contact the above with the substrate for the enzyme; (5) contact the above with a color reagent; (6) observe color change.

[0073] The antibody-containing sample of this method can comprise any biological sample which would contain the antibody or a cell containing the antibody, such as blood, plasma, serum, bone marrow, saliva and urine.

[0074] By the “suitability of an AAV4 vector for administration to a subject” is meant a determination of whether the AAV4 vector will elicit a neutralizing immune response upon administration to a particular subject. A vector that does not elicit a significant immune response is a potentially suitable vector, whereas a vector that elicits a significant, neutralizing immune response is thus indicated to be unsuitable for use in that subject. Significance of any detectable immune response is a standard parameter understood by the skilled artisan in the field. For example, one can incubate the subject's serum with the virus, then determine whether that virus retains its ability to transduce cells in culture. If such virus cannot transduce cells in culture, the vector likely has elicited a significant immune response.

[0075] The present method further provides a method of delivering a nucleic acid to a cell comprising administering to the cell an AAV4 particle containing a vector comprising the nucleic acid inserted between a pair of AAV inverted terminal repeats, thereby delivering the nucleic acid to the cell. Administration to the cell can be accomplished by any means, including simply contacting the particle, optionally contained in a desired liquid such as tissue culture medium, or a buffered saline solution, with the cells. The particle can be allowed to remain in contact with the cells for any desired length of time, and typically the particle is administered and allowed to remain indefinitely. For such in vitro methods, the virus can be administered to the cell by standard viral transduction methods, as known in the art and as exemplified herein. Titers of virus to administer can vary, particularly depending upon the cell type, but will be typical of that used for AAV transduction in general. Additionally the titers used to transduce the particular cells in the present examples can be utilized. The cells can include any desired cell, such as the following cells and cells derived from the following tissues, in humans as well as other mammals, such as primates, horse, sheep, goat, pig, dog, rat, and mouse: Adipocytes, Adenocyte, Adrenal cortex, Amnion, Aorta, Ascites, Astrocyte, Bladder, Bone, Bone marrow, Brain, Breast, Bronchus, Cardiac muscle, Cecum, Cervix, Chorion, Colon, Conjunctiva, Connective tissue, Cornea, Dermis, Duodenum, Endometrium, Endothelium, Epithelial tissue, Epidermis, Esophagus, Eye, Fascia, Fibroblasts, Foreskin, Gastric, Glial cells, Glioblast, Gonad, Hepatic cells, Histocyte, Ileum, Intestine, small Intestine, Jejunum, Keratinocytes, Kidney, Larynx, Leukocytes, Lipocyte, Liver, Lung, Lymph node, Lymphoblast, Lymphocytes, Macrophages, Mammary alveolar nodule, Mammary gland, Mastocyte, Maxilla, Melanocytes, Monocytes, Mouth, Myelin, Nervous tissue, Neuroblast, Neurons, Neuroglia, Osteoblasts, Osteogenic cells, Ovary, Palate, Pancreas, Papilloma, Peritoneum, Pituicytes, Pharynx, Placenta, Plasma cells, Pleura, Prostate, Rectum, Salivary gland, Skeletal muscle, Skin, Smooth muscle, Somatic, Spleen, Squamous, Stomach, Submandibular gland, Submaxillary gland, Synoviocytes, Testis, Thymus, Thyroid, Trabeculae, Trachea, Turbinate, Umbilical cord, Ureter, and Uterus.

[0076] The AAV inverted terminal repeats in the vector for the herein described delivery methods can be AAV4 inverted terminal repeats. Specifically, they can comprise the nucleic acid whose nucleotide sequence is set forth in SEQ ID NO:6 or the nucleic acid whose nucleotide sequence is set forth in SEQ ID NO:20, or any fragment thereof demonstrated to have ITR functioning. The ITRs can also consist essentially of the nucleic acid whose nucleotide sequence is set forth in SEQ ID NO:6 or the nucleic acid whose nucleotide sequence is set forth in SEQ ID NO:20. Furthermore, the AAV inverted terminal repeats in the vector for the herein described nucleic acid delivery methods can also comprise AAV2 inverted terminal repeats. Additionally, the AAV inverted terminal repeats in the vector for this delivery method can also consist essentially of AAV2 inverted terminal repeats.

[0077] The present invention also includes a method of delivering a nucleic acid to a subject comprising administering to a cell from the subject an AAV4 particle comprising the nucleic acid inserted between a pair of AAV inverted terminal repeats, and returning the cell to the subject, thereby delivering the nucleic acid to the subject. The AAV ITRs can be any AAV ITRs, including AAV4 ITRs and AAV2 ITRs. For such an ex vivo administration, cells are isolated from a subject by standard means according to the cell type and placed in appropriate culture medium, again according to cell type (see, e.g., ATCC catalog). Viral particles are then contacted with the cells as described above, and the virus is allowed to transfect the cells. Cells can then be transplanted back into the subject's body, again by means standard for the cell type and tissue (e. g., in general, U.S. Pat. No. 5,399,346; for neural cells, Dunnett, S. B. and Björklund, A., eds., Transplantation: Neural Transplantation-A Practical Approach, Oxford University Press, Oxford (1992)). If desired, prior to transplantation, the cells can be studied for degree of transfection by the virus, by known detection means and as described herein. Cells for ex vivo transfection followed by transplantation into a subject can be selected from those listed above, or can be any other selected cell. Preferably, a selected cell type is examined for its capability to be transfected by AAV4. Preferably, the selected cell will be a cell readily transduced with AAV4 particles; however, depending upon the application, even cells with relatively low transduction efficiencies can be useful, particularly if the cell is from a tissue or organ in which even production of a small amount of the protein or antisense RNA encoded by the vector will be beneficial to the subject.

[0078] The present invention further provides a method of delivering a nucleic acid to a cell in a subject comprising administering to the subject an AAV4 particle comprising the nucleic acid inserted between a pair of AAV inverted terminal repeats, thereby delivering the nucleic acid to a cell in the subject. Administration can be an ex vivo administration directly to a cell removed from a subject, such as any of the cells listed above, followed by replacement of the cell back into the subject, or administration can be in vivo administration to a cell in the subject. For ex vivo administration, cells are isolated from a subject by standard means according to the cell type and placed in appropriate culture medium, again according to cell type (see, e.g., ATCC catalog). Viral particles are then contacted with the cells as described above, and the virus is allowed to transfect the cells. Cells can then be transplanted back into the subject's body, again by means standard for the cell type and tissue (e. g., for neural cells, Dunnett, S. B. and Björklund, A., eds., Transplantation: Neural Transplantation-A Practical Approach, Oxford University Press, Oxford (1992)). If desired, prior to transplantation, the cells can be studied for degree of transfection by the virus, by known detection means and as described herein.

[0079] In vivo administration to a human subject or an animal model can be by any of many standard means for administering viruses, depending upon the target organ, tissue or cell. Virus particles can be administered orally, parenterally (e.g., intravenously), by intramuscular injection, by direct tissue or organ injection, by intraperitoneal injection, topically, transdermally, or the like. Viral nucleic acids (non-encapsidated) can be administered, e.g., as a complex with cationic liposomes, or encapsulated in anionic liposomes. Compositions can include various amounts of the selected viral particle or non-encapsidated viral nucleic acid in combination with a pharmaceutically acceptable carrier and, in addition, if desired, may include other medicinal agents, pharmaceutical agents, carriers, adjuvants, diluents, etc. Parental administration, if used, is generally characterized by injection. Injectables can be prepared in conventional forms, either as liquid solutions or suspensions, solid forms suitable for solution or suspension in liquid prior to injection, or as emulsions. Dosages will depend upon the mode of administration, the disease or condition to be treated, and the individual subject's condition, but will be that dosage typical for and used in administration of other AAV vectors, such as AAV2 vectors. Often a single dose can be sufficient; however, the dose can be repeated if desirable.

[0080] The present invention further provides a method of delivering a nucleic acid to a cell in a subject having antibodies to AAV2 comprising administering to the subject an AAV4 particle comprising the nucleic acid, thereby delivering the nucleic acid to a cell in the subject. A subject that has antibodies to AAV2 can readily be determined by any of several known means, such as contacting AAV2 protein(s) with an antibody-containing sample, such as blood, from a subject and detecting an antigen-antibody reaction in the sample. Delivery of the AAV4 particle can be by either ex vivo or in vivo administration as herein described. Thus, a subject who might have an adverse immunogenic reaction to a vector administered in an AAV2 viral particle can have a desired nucleic acid delivered using an AAV4 particle. This delivery system can be particularly useful for subjects who have received therapy utilizing AAV2 particles in the past and have developed antibodies to AAV2. An AAV4 regimen can now be substituted to deliver the desired nucleic acid.

STATEMENT OF UTILITY

[0081] The present invention provides recombinant vectors based on AAV4. Such vectors may be useful for transducing erythroid progenitor cells which is very inefficient with AAV2 based vectors. In addition to transduction of other cell types, transduction of erythroid cells would be useful for the treatment of cancer and genetic diseases which can be corrected by bone marrow transplants using matched donors. Some examples of this type of treatment include, but are not limited to, the introduction of a therapeutic gene such as genes encoding interferons, interleukins, tumor necrosis factors, adenosine deaminase, cellular growth factors such as lymphokines, blood coagulation factors such as factor VIII and IX, cholesterol metabolism uptake and transport protein such as EpoE and LDL receptor, and antisense sequences to inhibit viral replication of, for example, hepatitis or HIV.

[0082] The present invention provides a vector comprising the AAV4 virus as well as AAV4 viral particles. While AAV4 is similar to AAV2, the two viruses are found herein to be physically and genetically distinct. These differences endow AAV4 with some unique advantages which better suit it as a vector for gene therapy. For example, the wt AAV4 genome is larger than AAV2, allowing for efficient encapsidation of a larger recombinant genome. Furthermore, wt AAV4 particles have a greater buoyant density than AAV2 particles and therefore are more easily separated from contaminating helper virus and empty AAV particles than AAV2-based particles.

[0083] Furthermore, as shown herein, AAV4 capsid protein is distinct from AAV2 capsid protein and exhibits different tissue tropism. AAV2 and AAV4 are shown herein to utilize distinct cellular receptors. AAV2 and AAV4 have been shown to be serologically distinct and thus, in a gene therapy application, AAV4 would allow for transduction of a patient who already possess neutralizing antibodies to AAV2 either as a result of natural immunological defense or from prior exposure to AAV2 vectors.

[0084] The present invention is more particularly described in the following examples which are intended as illustrative only since numerous modifications and variations therein will be apparent to those skilled in the art.

EXAMPLES

[0085] To understand the nature of AAV4 virus and to determine its usefulness as a vector for gene transfer, it was cloned and sequenced.

[0086] Cell Culture and Virus Propagation

[0087] Cos and HeLa cells were maintained as monolayer cultures in D10 medium (Dulbecco's modified Eagle's medium containing 10% fetal calf serum, loo ug/ml penicillin, 100 units/ml streptomycin and IX Fungizone as recommended by the manufacturer; (GIBCO, Gaithersburg, Md., USA) . All other cell types were grown under standard conditions which have been previously reported. AAV4 stocks were obtained from American Type Culture Collection #VR-64 6.

[0088] Virus was produced as previously described for AAV2 using the Beta galactosidase vector plasmid and a helper plasmid containing the AAV4 Rep and Cap genes (9). The helper plasmid was constructed in such a way as not to allow any homologous sequence between the helper and vector plasmids. This step was taken to minimize the potential for wild-type (wt) particle formation by homologous recombination.

[0089] Virus was isolated from 5×10⁷ cos cells by CsCl banding (9), and the distribution of Beta galactosidase genomes across the genome was determined by DNA dot blots of aliquots of gradient fractions. The majority of packaged genomes were found in fractions with a density of 1.43 which is similar to that reported for wt AAV4. This preparation of virus yielded 2.5×10¹¹ particles or 5000 particles/producer cell. In comparison AAV2 isolated and CsCl banded from 8×10⁷ cells yielded 1.2×10¹¹ particles or 1500 particles/producer cell. Thus, typical yields of rAAV4 particles/producer cell were 3-5 fold greater than that of rAAV2 particles.

[0090] DNA Cloning and Sequencing and Analysis

[0091] In order to clone the genome of AAV4, viral lysate was amplified in cos cells and then HeLa cells with the resulting viral particles isolated by CsCl banding. DNA dot blots of aliquots of the gradient fractions indicated that peak genomes were contained in fractions with a density of 1.41-1.45. This is very similar to the buoyant density previously reported for AAV4 (29). Analysis of annealed DNA obtained from these fractions indicated a major species of 4.8 kb in length which upon restriction analysis gave bands similar in size to those previously reported. Additional restriction analysis indicated the presence of BssHII restriction sites near the ends of the DNA. Digestion with BssHII yielded a 4.5 kb fragment which was then cloned into Bluescript SKII+ and two independent clones were sequenced.

[0092] The viral sequence is now available through Genebank, accession number U89790. DNA sequence was determined using an ABI 373A automated sequencer and the FS dye terminator chemistry. Both strands of the plasmids were sequenced and confirmed by sequencing of a second clone. As further confirmation of the authenticity of the sequence, bases 91-600 were PCR amlified from the original seed material and directly sequenced. The sequence of this region, which contains a 56 base insertion compared to AAV2 and 3, was found to be identical to that derived from the cloned material. The ITR was cloned using Deep Vent Polymerase (New England Biolabs) according to the manufactures instructions using the following primers, primer 1: 5′TCTAGTCTAGACTTGGCCACTCCCTCTCTGCGCGC(SEQ ID NO:21); primer 2: 51 AGGCCTTAAGAGCAGTCGTCCACCACCTTGTTCC (SEQ ID NO:22). Cycling conditions were 97° C. 20 sec, 65° C. 30 sec, 75° C. 1 min for 35 rounds. Following the PCR reaction, the mixture was treated with XbaI and EcoRI endonucleases and the amplified band purified by agarose gel electrophoresis. The recovered DNA fragment was ligated into Bluescript SKII+ (Stratagene) and transformed into competent Sure strain bacteria (Stratagene). The helper plasmid (pSV40oriAAV₄₋₂) used for the production of recombinant virus, which contains the rep and cap genes of AAV4, was produced by PCR with Pfu polymerase (Stratagene) according to the manufactures instructions. The amplified sequence, nt 216-4440, was ligated into a plasmid that contains the SV40 origin of replication previously described (9, 10). Cycling conditions were 95° C. 30 sec, 55° C. 30 sec, 72° C. 3 min for 20 rounds. The final clone was confirmed by sequencing. The βgal reporter vector has been described previously (9, 10).

[0093] Sequencing of this fragment revealed two open reading frames (ORF) instead of only one as previously suggested. In addition to the previously identified Capsid ORF in the right-hand side of the genome, an additional ORF is present on the left-hand side. Computer analysis indicated that the left-hand ORF has a high degree of homology to the Rep gene of AAV2. At the amino acid level the ORF is 90% identical to that of AAV2 with only 5% of the changes being non-conserved (SEQ ID NO:2). In contrast, the right ORF is only 62% identical at the amino acid level when compared to the corrected AAV2 sequence. While the internal start site of VP2 appears to be conserved, the start site for VP3 is in the middle of one of the two blocks of divergent sequence. The second divergent block is in the middle of VP3. By using three dimensional structure analysis of the canine parvovirus and computer aided sequence comparisons, regions of AAV2 which might be exposed on the surface of the virus have been identified. Comparison of the AAV2 and AAV4 sequences indicates that these regions are not well conserved between the two viruses and suggests altered tissue tropism for the two viruses.

[0094] Comparison of the p5 promoter region of the two viruses shows a high degree of conservation of known functional elements (SEQ ID NO:7). Initial work by Chang et al. identified two YY1 binding sites at −60 and +1 and a TATA Box at −30 which are all conserved between AAV2 and AAV4 (4). A binding site for the Rep has been identified in the p5 promoter at −17 and is also conserved (24). The only divergence between the two viruses in this region appears to be in the sequence surrounding these elements. AAV4 also contains an additional 56 bases in this region between the p5 promoter and the TRS (nt 209-269). Based on its positioning in the viral genome and efficient use of the limited genome space, this sequence may possess some promoter activity or be involved in rescue, replication or packaging of the virus.

[0095] The inverted terminal repeats were cloned by PCR using a probe derived from the terminal resolution site (TRS)of the BssHII fragment and a primer in the Rep ORF. The TRS is a sequence at the end of the stem of the ITR and the reverse compliment of TRS sequence was contained within the BssHII fragment. The resulting fragments were cloned and found to contain a number of sequence changes compared to AAV2. However, these changes were found to be complementary and did not affect the ability of this region to fold into a hairpin structure (FIG. 2). While the TRS site was conserved between AAV2 and AAV4 the Rep binding site contained two alterations which expand the binding site from 3 GAGC repeats to 4. The first two repeats in AAV4 both contain a T in the fourth position instead of a C. This type of repeat is present in the p5 promoter and is present in the consensus sequence that has been proposed for Rep binding (10) and its expansion may affect its affinity for Rep. Methylation interference data has suggested the importance of the CTTTG motif found at the tip of one palindrome in Rep binding with the underlined T residues clearly affecting Rep binding to both the flip and flop forms. While most of this motif is conserved in AAV4 the middle T residue is changed to a C (33).

[0096] Hemagglutination Assays

[0097] Hemagglutination was measured essentially as described previously (18). Serial two fold dilutions of virus in Veronal-buffered saline were mixed with an equal volume of 0.4% human erythrocytes (type 0) in plastic U bottom 96 well plates. The reaction was complete after a 2 hr incubation at 8° C. HA units (HAU) are defined as the reciprocal of the dilution causing 50% hemagglutination.

[0098] The results show that both the wild type and recombinant AAV4 viruses can hemagglutinate human red blood cells (RBCS) with HA titers of approximately 1024 HAU/μl and 512 HAU/μl respectively. No HA activity was detected with AAV type 3 or recombinant AAV type 2 as well as the helper adenovirus. If the temperature was raised to 22° C., HA activity decreased 32-fold. Comparison of the viral particle number per RBC at the end point dilution indicated that approximately 1-10 particles per RBC were required for hemagglutination. This value is similar to that previously reported (18).

[0099] Tissue Tropism Analysis

[0100] The sequence divergence in the capsid proteins ORF which are predicted to be exposed on the surface of the virus may result in an altered binding specificity for AAV4 compared to AAV2. Very little is known about the tissue tropism of any dependovirus. While it had been shown to hemagglutinate human, guinea pig, and sheep erythrocytes, it is thought to be exclusively a simian virus (18). Therefore, to examine AAV4 tissue tropism and its species specificity, recombinant AAV4 particles which contained the gene for nuclear localized Beta galactosidase were constructed. Because of the similarity in genetic organization of AAV4 and AAV2, it was determined whether AAV4 particles could be constructed containing a recombinant genome. Furthermore, because of the structural similarities of the AAV type 2 and type 4 ITRs, a genome containing AAV2 ITRs which had been previously described was used.

[0101] Tissue Tropism Analysis 1.

[0102] To study AAV transduction, a variety of cell lines were transduced with 5 fold serial dilutions of either recombinant AAV2 or AAV4 particles expressing the gene for nuclear localized Beta galactosidase activity (Table 1). Approximately 4×10⁴ cells were exposed to virus in 0.5 ml serum free media for 1 hour and then 1 ml of the appropriate complete media was added and the cells were incubated for 48-60 hours. The cells were then fixed and stained for β-galactosidase activity with 5-Bromo-4-Chloro-3-Indolyl-β-D-galactopyranoside (Xgal) (ICN Biomedicals) (36). Biological titers were determined by counting the number of positive cells in the different dilutions using a calibrated microscope ocular (3.1 mm²) then multiplying by the area of the well and the dilution of the virus. Typically dilutions which gave 1-10 positive cells per field (100-1000 positive cells per 2 cm well) were used for titer determination. Titers were determined by the average number of cells in a minimum of 10 fields/well.

[0103] To examine difference in tissue tropism, a number of cell lines were transduced with serial dilutions of either AAV4 or AAV2 and the biological titers determined. As shown in Table 1, when Cos cells were transduced with a similar number of viral particles, a similar level of transduction was observed with AAV2 and AAV4. However, other cell lines exhibited differential transducibility by AAV2 or AAV4. Transduction of the human colon adenocarcinoma cell line SW480 with AAV2 was over 100 times higher than that obtained with AAV4. Furthermore, both vectors transduced SW1116, SW1463 and NIH3T3 cells relatively poorly. TABLE 1 Cell type AAV2 AAV4 Cos 4.5 × 10⁷ 1.9 × 10⁷   SW480 3.8 × 10⁶ 2.8 × 10⁴   SW1116 5.2 × 10⁴ 8 × 10³ SW1463 8.8 × 10⁴ 8 × 10³ SW620 8.8 × 10⁴ ND NIH3T3   2 × 10⁴ 8 × 10³

[0104] Tissue Tropism Analysis 2.

[0105] A. Transduction of Cells.

[0106] Exponentially growing cells (2×10⁴) were plated in each well of a 12 well plate and transduced with serial dilutions of virus in 200 μl of medium for 1 hr. After this period, 800 μl of additional medium was added and incubated for 48 hrs. The cells were then fixed and stained for β-galactosidase activity overnight with 5-bromo-4-chloro-3-indolyl-β-D-galactopyranoside (Xgal) (ICN Biomedicals) (36). No endogenous β-galactosidase activity was visible after 24 hr incubation in Xgal solution. Infectious titers were determined by counting the number of positive cells in the different dilutions using a calibrated microscope ocular (diameter 3.1 mm² ) then multiplying by the area of the well and the dilution of the virus. Titers were determined by the average number of cells in a minimum of 10 fields/well.

[0107] As shown in Table 2, cos cells transduced with equivalent amounts of rAAV2 and rAAV4particles resulted in similar transduction levels. However, other cell lines exhibited differential transducibility. Transduction of the human colon adenocarcinoma cell line, SW480, with rAAV2 was 60 times higher than that obtained with rAAV4. Hela and SW620 cells were also transduced more efficiently with rAAV2 than rAAV4. In contrast, transduction of primary rat brain cultures exhibited a greater transduction of glial and neuronal cells with rAAV4 compared to rAAV2. Because of the heterogeneous nature of the cell population in the rat brain cultures, only relative transduction efficiencies are reported (Table 2).

[0108] As a control for adenovirus contamination of the viral preparations cos and Hela cells were coinfected with RAAV and adenovirus then stained after 24 hr. While the titer of rAAV2 increased in the presence of Ad in both cos and Hela, adenovirus only increased the titer in the cos cells transduced with rAAV4 and not the HeLa cells, suggesting the difference in transduction efficiencies is not the result of adenovirus contamination. Furthermore, both vectors transduced SW1116, SW1463, NIH3T3 and monkey fibroblasts FL2 cells very poorly. Thus AAV4 may utilize a cellular receptor distinct from that of AAV2. TABLE 2 CELL TYPE AAV2 AAV4 Primary Rat Brain 1 4.3 ± 0.7   cos 4.2 × 10⁷ ± 4.6 × 10⁶ 2.2 × 10⁷ ± 2.5 × 10⁶ SW480 7.75 × 10⁶ ± 1.7 × 10⁶  1.3 × 10⁵ ± 6.8 × 10⁴ Hela 2.1 × 10⁷ ± 1 × 10⁶   1.3 × 10⁶ ± 1 × 10⁵    SW620 1.2 × 10⁵ ± 3.9 × 10⁴ 4 × 10⁴ KLEB 1.2 × 10⁵ ± 3.5 × 10⁴   9 × 10⁴ ± 1.4 × 10⁴ HB 5.6 × 10⁵ ± 2 × 10⁵   3.8 × 10⁴ ± 1.8 × 10⁴ SW1116 5.2 × 10⁴ 8 × 10³ SW1463 8.8 × 10⁴ 8 × 10³ NIH3T3   3 × 10³ 2 × 10³

[0109] B. Competition Assay.

[0110] Cos cells were plated at 2×10⁴/well in 12 well plates 12-24 hrs prior to transduction. Cells were transduced with 0.5×10⁷ particles of rAAV2 or rAAV4 (containing the LacZ gene) in 200 μl of DMEM and increasing amounts of rAAV2 containing the gene for the human coagulation factor IX. Prior to transduction the CsCl was removed from the virus by dialysis against isotonic saline. After 1 hr incubation with the recombinant virus the culture medium was supplemented with complete medium and allowed to incubate for 48-60 hrs. The cells were then stained and counted as described above.

[0111] AAV4 utilization of a cellular receptor distinct from that of AAV2 was further examined by cotransduction experiments with rAAV2 and rAAV4. Cos cells were transduced with an equal number of rAAV2 or rAAV4 particles containing the LacZ gene and increasing amounts of rAAV2 particles containing the human coagulation factor IX gene (rAAV2FIX). At a 72:1 ratio of rAAV2FIX:rAAV4LacZ only a two-fold effect on the level of rAAV4LacZ transduction was obtained (FIG. 3). However this same ratio of rAAV2FIX:rAAV2LacZ reduced the transduction efficiency of rAAV2LacZ approximately 10 fold. Comparison of the 50% inhibition points for the two viruses indicated a 7 fold difference in sensitivity.

[0112] C. Trypsinization of Cells.

[0113] An 80% confluent monolayer of cos cells (1×10⁷) was treated with 0.05% trypsin/0.02% versene solution (Biofluids) for 3-5 min at 37° C. Following detachment the trypsin was inactivated by the addition of an equal volume of media containing 10% fetal calf serum. The cells were then further diluted to a final concentration of 1×10⁴/ml. One ml of cells was plated in a 12 well dish and incubated with virus at a multiplicity of infection (MOI) of 260 for 1-2 hrs. Following attachment of the cells the media containing the virus was removed, the cells washed and fresh media was added. Control cells were plated at the same time but were not transduced until the next day. Transduction conditions were done as described above for the trypsinized cell group. The number of transduced cells was determined by staining 48-60 hrs post transduction and counted as described above.

[0114] Previous research had shown that binding and infection of AAV2 is inhibited by trypsin treatment of cells (26). Transduction of cos cells with rAAV21acZ gene was also inhibited by trypsin treatment prior to transduction (FIG. 4). In contrast trypsin treatment had a minimal effect on rAAV41acZ transduction. This result and the previous competition experiment are both consistent with the utilization of distinct cellular receptors for AAV2 and AAV4.

[0115] AAV4 is a distinct virus based on sequence analysis, physical properties of the virion, hemagglutination activity, and tissue tropism. The sequence data indicates that AAV4 is a distinct virus from that of AAV2. In contrast to original reports, AAV4 contains two open reading frames which code for either Rep proteins or Capsid proteins. AAV4 contains additional sequence upstream of the p5 promoter which may affect promoter activity, packaging or particle stability. Furthermore, AAV4 contains an expanded Rep binding site in its ITR which could alter its activity as an origin of replication or promoter. The majority of the differences in the Capsid proteins lies in regions which have been proposed to be on the exterior surface of the parvovirus. These changes are most likely responsible for the lack of cross reacting antibodies, hemagglutinate activity, and the altered tissue tropism compared to AAV2. Furthermore, in contrast to previous reports AAV4 is able to transduce human as well as monkey cells.
